Inactivation of Enterococcus sp. by photolysis and TiO2 photocatalysis with H2O2 in natural water

► Solar radiation, TiO2 and H2O2 as disinfectant treatments on Enterococcus sp. ► Study of intermittent/continuous radiation and bacterial recovery in darkness conditions. ► Powerful disinfectant effect of UVB on bacteria regarding the rest of solar radiation. ► Similar inactivation levels with continuous and intermittent illumination. ► No change or else a slight recovery of the bacterial population in darkness conditions.
